The chief of the emergency response services claims that their team responds to emergency distress calls within a 5 km radius in 360 seconds. An independent investigator wishes to test whether or not the presence of a thousand extra cars within the 5 km radius affects the emergency response time by 8.65 seconds. He randomly selects 100 distress calls and estimates the following regression: A Yr- 2 350 + 0.23m, where '3}; denotes the predicted response time measured in seconds tor the if\" emergency call and Xr denotes the number of cars {in thousands) on the road within a 5 km radius at the time of the if};1 emergency call. If 1 is the slope coefcient, which of the following options states the investigator's null and alternative hypotheses? A. H04?1 :3 8.65 and H1:,6158.65. .V 3. H0: ,61 = 8.65 and H1: .61 i 3.65. ' c. H0:,61= 0.23 and H1:,61 0.23. D. H0431: 0.23 and H1:,61s 0.23. Suppose ltal associated with the test the investigator wishes to conduct is 2.21. The pvalue will be (Round your answer to three decimal\" places.)
